Claimant has worked for Harley-Davidson for 16 years. In January of 2012, Claimant's primary job was in the Quality section which involved data entry and some desk work. Claimant, who I find credibly testified, had no prior symptoms of right elbow pain until January 3, 2012. Around that time period, Claimant was pulled from the Quality Department and filling in the Fabrication Department at the beginning of the year through most of the second half of 2012. On January 3, 2012, he filled in Fabrication a full day. He filled various positions in the Fabrication Department depending on staffing, who was working and who was on vacation. At times, he would go weekly, sometimes multiple times a week during the time period of January 3,2012 to the present.
The various jobs in Fabrication consisted of repetitive use of upper extremities from knee to shoulder between 39 and 50 inches while obtaining parts and components. It also involved using upper extremities to place components on the welding fixture and transferring the completed item to the assembly line. It was noted in the Ergonomic Job Measurement System (Exhibit B, p. 32-53) that there is a moderate amount of elbow and arm flexion as well as finger and hand motion performing the various duties in Fabrication. The Ergonomic Job Measurement System presented into evidence reveals that this type of repetitive motion regarding arm and elbow flexion/extension was required in frames, the Dyna tanks department, and sanding Dyna tanks as well as many other positions Claimant performed while in Fabrication. (Exhibit B, p. 32-53)
Claimant, when he worked in the Dyna fuel tank area, would at times have to load tanks into a weld fixture, begin the weld cycle, pin-stamp, and push and pull carts, all using his upper extremities. When he polished the tanks, he used his arm and elbow in a flexion/extension motion to polish the machinery while moving the tanks. Indeed, the Ergonomic Job Measurement System (Exhibit B, p. 32-53) indicated that there was a moderate amount of repetitive arm motion in a sustained awkward position when performing these job duties in Fabrication. I find those positions in Fabrication that Claimant performed from January 3, 2012 and continuing each and every day thereafter were repetitive. This finding is based on Claimant's testimony and evidence presented at hearing.
The issue to be addressed by this hearing is whether those repetitive job tasks as outlined in Exhibit B were causally related to Claimant's diagnosis of right lateral epicondylitis and radial synovitis. In this case, Claimant received treatment from doctors working in the medical facilities located at the Harley-Davidson plant. Records generated close in time reveal right elbow symptoms started "since the inception of the four 10 -hour days he has been out on the line." Records of January 24, 2012 indicate complaints of tenderness around the right forearm and elbow. On January 25, medical records show right elbow pain since changing job duties on January 3, 2012. These records corroborate Claimant's testimony that the majority of his job in January consisted of performing repetitive motion of his upper extremity by filling in on the line.
Doctors at the on-site facility diagnosed Claimant with mild right carpal tunnel syndrome
and early cubital tunnel syndrome based on an EMG that was obtained on March 22, 2002. On May 1, 2012, records reveal further treatment of his right elbow was denied due to outside activities. The medical record stated that Claimant had been bow and gun hunting and, as such, no further treatment would be provided. At that time, a formal claim was filed.
The parties presented two experts. Both experts agree Claimant has right lateral epicondylitis and radial synovitis. Dr. Poppa found based on Claimant's job description, medical records and physical examination that Claimant had not reached maximum medical improvement, that Claimant's diagnosis of the right elbow is related to the repetitive activities that occurred around January 3, 2012 and continuing each and every day thereafter. Dr. Poppa found the lifting and working in the Dyna tank department with his arms extended for long periods of time involved overuse of his right upper extremity to cause the lateral epicondylitis of the right elbow. Dr. Poppa found that the work-related injury was the prevailing factor causing the medical condition. Dr. Poppa recommended a series of cortisone injections involving the right elbow, physical therapy and, if the conservative treatment should fail, then surgical intervention of the right elbow.
The Employer's expert, Dr. Lingenfelter, found that Claimant had right lateral epicondylitis and radial synovitis. Dr. Lingenfelter stated the outside activities of hunting would not cause right lateral epicondylitis and radial synovitis. It appears from Dr. Lingenfelter's testimony that he received information regarding the quality manager position and the job Claimant performed on January 3, 2012. Dr. Lingenfelter stated, based on the quality manager position which was the desk job and the fabrication duties he performed on January 3, 2012, that Claimant did not perform repetitive tasks long enough to develop the right lateral epicondylitis and radial synovitis. Instead, Dr. Lingenfelter felt that Claimant needed to be exposed on a sustained period of time, such as three or four weeks in order for the job duties in Fabrication to be the prevailing factor of right epicondylitis and radial synovitis. (Exhibit C, p. 43)
In this case with these particular set of facts, I do not rely on Dr. Lingenfelter's opinion because I do not find Dr. Lingenfelter had all the facts surrounding the job duties Claimant performed and the length of time he performed them. For example, Dr. Lingenfelter admitted he would need to see how the Dyna tank job was performed in order to determine whether or not that job was a repetitive job. (Exhibit C, p. 9-10) Indeed, Dr. Lingenfelter did not recall seeing a description of the tank welding scale that showed a three regarding hazards severity and risk probability for developing repetitive motion injuries when the scale is one to three with three the highest. (Exhibit C, Deposition Ex. 2) Therefore, I do not find Dr. Lingenfelter had all of the facts and information needed in order to derive his opinion.
As such, I find based on the evidence presented that Claimant sustained his burden of proof. I find that the work activities that Claimant performed on or about January 3, 2012 and continuing thereafter consisted of repetitive exposure of his upper extremities and was the prevailing factor of Claimant's right elbow condition. Claimant specifically when working in the fabrication line on the Dyna tanks, but not limited to the Dyna tanks position, was exposed to repetitive extension and flexion of his elbow that caused right lateral epicondylitis and radial
